JURY RUDDER.

APPLICATION FILED DEC. 20, 1907.

5 E E 5 w W UNTT WILLIAM MANWARING, OF TROY, NEW YORK.

JURY-RUDDEB To all whom it may concern:

Be it known that T, TVILLIAM Man warm G,

a subject of the King of Great Britain, residing at Troy, county of Rensselaer, and State of New York, have invented certain new and useful improvements in Jury-Rudders, of which the following is a specification.

The invention relates to such improvements and consists of the novel construction nd combination of parts hereinafter de scribel and subsequently claimed.

Reference may be had to the accompany ing drawings, and the reference characters marked thereon, which form a part of this specification.

Similar characters refer to similar parts in the several figures therein.

F'gure 1. of the drawings is a view in side elevation of the stern of a vessel provided with the improved jury-rudder. Fig. 2 is a plan view of one of the triangular plates which are riveted together to form the drag. Z3 is an edge view of the plate shown in Fig. 1. Fig" '1- is a top plan view of the parts shown in l- 1, the movements of the rudder being indicated by dotted lines. F ig. 5 is a vertical section taken on the broken line, 5-5, in Fig. l.

The object of the invention is to provide a substitute for a disabled rudder by means of which a vessel can be kept in its proper course.

The invention consists of a drag and means for moving the drag transversely of the course of the vessel, as will be hereinafter more fully described and subsequently pointed out in the claim.

The drawings show the stern, 1, of a vessel {the other portion of the vessel being broken away for convenience in illustration) provided with the usual capstan, 2, and a spar, 3, extending transversely of the vessel and secured thereto in some suitable manner, as by means of the plates, it, rotatively mounted upon and supported by the pivotstuds, (3, proj cting from the upper ends of the post, 5, Fig. 1. The plates are provided 1 with the cam-like pro ection, 7, adapted to sicurely hold the spar, 3, in the position shown in Fig. when the plates are turned so that the projection, 7, comes in contact with the spar as seen in said figure.

pulley, 10, over which passes the endless wire 12. This wire is 'iven several turns around Specification of Letters Patent.

Each I end of the spar is provided with a gu1de- Patented July 20, 1909.

the capstan, and is also connected with the drag, 9, by means of bridle or angle-lines, 13, connected one to each corner of the front side of the drag at one end, the other end of each line being connected with a ring, 14, inserted in the ring, 15, secured to the endless wire.

By moving the drag to port, to the position shown by dotted lines, 17 the course of the vessel can be changed in the same manner that it would be changed by the use of the ordinary rudder, and by changing the position of the drag to starboard, to the position shown by dotted lines, 18, the course of the vessel can be again changed in the opposite direction.

The improved means for changing the position of the drag relatively to the course of the vessel may be employed in connection with any known form of drag.

A preferred and improved form of drag is shown in the drawings consisting of four triangular metallic plates, three of which are like plate, 20, shown in Figs. 2 and 3. The three plates, 20, form the upright walls of the drag and are each provided with edge flanges on the three triangular sides, the flange, 21, projecting in one direction, and the flanges, 22, on the other two sides of the triangular plate projecting in the opposite direction, as seen in Figs. 2 and 3. When the plates are fastened together the flanges, 2-2, lap one another and are secured together by rivets, n3,'as seen. in Fig. hen desired they may also be additionally secured by rivets 24. The fourth or bottom side plate, 25, has no edge flanges and is riveted to the lower edge flanges of the other three plates as seen in Fig. 5. Such a form of construction affords a water-tight compartment which will cause the drag to float in water.

The bottom plate may be weighted in any known manner, as by riveting to the inner side thereof a ballast-plate of metal, 26, by means of rivets 27. This ballast-plate may be made to taper in thickness, as shown by dotted lines, 28, in Fig. 1, so as to maintain the drag in the position shown in said figure with the front edge of the bottom plate in an approximately horizontal plane and the triangular plate ft cing the vessel in an approximately vertical plane, as shown in Fig. 1.

The corners of the drag may each be pro vided with an eye, 29, three of which are adapted to receive one end of one of the angle-lines 13. The eye on the rear corner of the drag is adapted to receive one end of the spilling-line, 30, by which the drag can be reversed when drawn on board the vessel in the usual manner. The vessel-end of the spilling-line can be secured in the usual manner to the c'leat, 31, on the vessel. A single capstan-bar, 32, is shown for rotating the capstan.

; The spar, 8, may be detachably secured to the vessel in any known manner, as by lashing with cords, whereby the apparatus can be stored away in some convenient place on the vessel until the rudder has become disabled or displaced, or the guide-pulleys over which the wire, 12, travels may be supported by a permanent projection from opposite sides of the Vessel. By the term wire it is intended to include any equivalent thereof, as cords or cables.

In F 1 of the drawings the drag is shown with a considerable portion above the level of the water. It is obvious that the normal immersion may be varied by varying the weight of the ballast plate, 26, shown in Fig. 5. It is also obvious that the deeper the immersion the greater the resistance to movement through the water, and the greater the efliciency of the drag as a steering device.

hat I claim as new and desire to secure by Letters Patent is A jury-rudder, comprising a tetrahedral drag made of four triangular plates riveted together along their edges, the bottom plate being weighted; and means for imparting to the drag lateral movements relatively to r the course of the vessel.

In testimony whereof, I have hereunto set my hand this 18th day of December, 1907.
